Evolution of sod-podzolic loamy bedrocks in zone floodings by a water basin of Kama

In zone floodings by a water basin of Kama in sod-podsolic loamy bedrocks educe the evolutionary changes which have shown in morphological change of physical and chemical properties. At a periodic water-stagnant mode are formed bedrocks with powerful podzolic horizons and high acidity. At a water-stagnant mode educe bogging and accumulation gumus materials
